The county level of basic public services analysis and classification play an important role in county economic growth and improve benefit of healthy development of urbanization in China. According to the county level of basic public services data which is large scale and imbalance, this paper presented a support vector machine model to classify the county level of basic public services. The method...
The AQM (Active Queue Management) Algorithm such as RED, PI, REM have too long respond time and some other problems. Though it makes some enhancement, the PID (Proportional Integral Differential) active queue management algorithm can not make the queue length converge to expectation with longer delay. Because of self-adapt control of BP (back-propagation) neural network, this issue bring forward a...
City innovative capability analysis and prediction play an important role in regional innovation systems development and improve benefit of innovative capability for country. According to the city innovative capability data which is large scale and imbalance, this paper presented a support vector machine model to predict city innovative capability. The method was compared with artificial neural network,...
Waveform signals of earthquake and explosion are nonlinear and non-stationary. A BP (Back-Propagation) neural network model is established to simulate the waveform signal of the earthquake and explosion based upon the real wave data on the Matlab 7.0 experiment platform. It is shown that the differences between the waveform signal simulated by BP neural network and the real waveform signal are quite...
Building a power quality monitoring and analysis system is important to improve power quality and avoid equipment damage. A new approach for power quality disturbance classification based on linear time-frequency distribution and rough membership neural networks is presented in this paper. Taken the advantages of windowed Fourier transform and S-transform, the approach presented five features to characterize...
The flight envelope of modern fighter aircraft has a wide range, and the power density of electronic equipments on board is also continuously increasing. For these reasons, the reliability of ECS (environmental control system) for fighter aircraft must be solved to guarantee pilot's safety and comfort, and to ensure the normal operation of electronic equipments on board. This paper focused on the...
This paper proposes a new recursive variable loading minimum variance distortionless response (RVL-MVDR) algorithm for robust beamforming in impulsive noise environment. It employs a new method for robust estimation of the sample covariance matrix under impulsive noise and a new method for computing the data-dependent loading level using robust statistics. Computer simulations suggest that the proposed...
